“…Results from various tests on palm kernel shells indicate that, for sieve analysis, specific gravity, and absorption, they meet SNI (Indonesian National Standards) standards, allowing their use as aggregate substitutes, not exceeding 10% for palm kernel boiler ash and not exceeding 30% for palm kernel shells. The average compressive strength on days 7 and 28 was obtained at 21 MPa, which did not meet the planned compressive strength of 25 MPa [7]. The average compressive strength results for each variation of palm kernel shell mixture, starting from 0%, 15%, 20%, and 25%, were 20.18 MPa, 17.20 MPa, 16.27 MPa, and 15.34 MPa, respectively.…”

This experimental study aims to evaluate the compressive strength of concrete using palm kernel shells as a substitution for coarse aggregates. The utilization of locally available materials in abundance, such as palm kernel shells, can serve as a sustainable alternative in construction. This research is conducted to measure the influence of palm kernel shell usage on the mechanical properties of concrete, particularly its compressive strength. The research methodology involves the preparation of concrete mixtures with various levels of substitution of coarse aggregates with palm kernel shells. Test specimens were prepared with substitution percentages of 0%, 25%, and 60% with planned ages of 7 days, 21 days, and 28 days. Three cube specimens were cast for each planned age. The test results were used to compare the compressive strength of concrete with and without palm kernel shells and to evaluate the potential of palm kernel shells as a substitute for coarse aggregates in structural concrete applications. The research findings indicate that the highest compressive strength was obtained in the concrete without any palm kernel shell mixture (0%), measuring 379.86 kg/cm2. The highest compressive strength with the substitution of coarse aggregates using palm kernel shells was found in the 25% mixture, with a value of 362.57 kg/cm2, while the lowest percentage was recorded in the 60% mixture, with a value of 270.65 kg/cm2. Palm kernel shells have the potential to be used as a substitute for coarse aggregates in concrete. However, their utilization needs to be carefully analyzed and tailored to the specific conditions and requirements of construction projects. This research provides initial insights into the use of palm kernel shells in concrete and can serve as a foundation for further research in the development of environmentally friendly concrete using sustainable local raw materials

Concrete is one of the most important materials used in building structures. A material that can be used to create normal concrete with this method is to add palm shell ash to the concrete mix. Palm shell ash can be used as a filler material, because the ash has a chemical composition contains silica (SiO2) which is amorphus and highly reactive at room temperature. The use of palm shell ash as an additive to the concrete mixture aims to improve the quality of the concrete which is planned after palm shell ash is added to the concrete mixture. The tests carried out in this study were compressive power, split tensile power, flexural power, and modulus of elasticity at the age of 28 days concrete. The number of samples made was 36 cylinders and 12 blocks for variations in percentage of 0%, 5%, 10%, 15%, 20% and 25%. The treatment of the specimens was done by immersing them for 26 days. The values of compressive power, split tensile power, flexural power, and elastic modulus will decrease when the percentage of palm shell ash in the concrete mixture increases. Abstrak Beton merupakan suatu material yang begitu vital untuk diaplikasikan dalam dunia konstruksi. Suatu materi yang bisa dimanfaatkan untuk menciptakan beton normal dengan metode ini adalah dengan menambahkan abu cangkang sawit ke dalam campuran beton. Abu cangkang sawit bisa dimanfaatkan selaku materi pengisi (filler), sebab abu tersebut memiliki kompenen kimia yang mengandung silika (SiO2) yang bersifat amorphus (bukan kristal) dan sangat reaktif pada temperature kamar. Penggunaan abu cangkang sawit selaku materi tambahan dalam campuran beton bertujuan untuk meningkatkan mutu beton yang direncanakan setelah abu cangkang sawit ditambahkan pada campuran beton. Percobaan yang diselenggarakan pada penelitian berikut adalah kuat tekan, kuat tarik belah, kuat lentur, dan modulus elastisitas terhadap usia beton 28 hari. Jumlah sampel yang dibuat adalah 36 buah berbentuk silinder dan 12 buah berbentuk balok dengan variasi persentase sebesar 0%, 5%, 10%, 15%, 20%, dan 25%. Perawatan materi pengujian dilakukan dengan upaya direndam dalam 26 hari. Hasil kuat tekan, kuat tarik belah, kuat lentur, dan modulus elastisitas menurun ketika persentase abu cangkang sawit pada campuran beton meningkat.

This study aims to analyze the nature of chemical content, analyze abrasion value and optimum asphalt content using local Kinang Jingkion as road pavement material. In this study, XRF and XRD testing methods were used to determine the chemical content of Kinang Jingkion local material, then testing the characteristics of rough aggregate to determine the abrasion value, testing fine aggregate characteristics, and testing asphalt pen 60/70 and marshall test to determine the optimum asphalt content (KAO). The tests obtained the results of comparative data analysis between laboratory tests and literature standards that meet the eligibility requirements. The results showed that: First, the results of XRF and XRD analysis on Wilihingke samples, 0.15 mm granules, 2.36 mm granules, and Kinang Holuwon found that all chemical elements contained in the four samples were solid metal inorganic chemical elements. The results of this analysis prove that the four samples, which are fine aggregates and coarse aggregates, do not contain organic substances. Where the results of this analysis are by the requirements of aggregates which are one of the components in the concrete mixture, where the aggregates used must meet certain conditions, one of which must not contain excess organic matter because it can undergo decay by bacteria using dissolved oxygen; Second, from the test results obtained, the aggregate wear value (abrasion) was 32.69%; Third, based on the test results, the value of the Marshall parameter with Optimum Asphalt Content (KAO) obtained a value of 6.125%.
